His hair is a curly brownish color. He has exceptionally hairy feet with the same brownish-curly hair like what is on his head. He's smaller than the rest of the hobbits because he is the youngest.
Pippin was the foolish, impulsive one. ("Fool of a Took!" and "No one asked you to handle that" --Gandalf) He almost got the company killed in the mines of Moria, by throwing a stone down a deep well; noise tipped off the orcs. He picked up the orb of Orthanc and then actually stole out of Gandalf's hands while he slept. Later, he redeems himself by running (against orders) to get Gandalf when Faramir's father was going to burn him alive. I'm sure Eowyn? appreciated that.
